Rabbi Chaim of Volozhin says, “Anyone that studies Torah for its own sake.” Some people may think that the idea of studying Torah for its own sake means studying in-order to come close to HaShem. According to that kind of logic a person should spend all their time singing praises to Him.” There is a Midrash that tells David requested of HaShem that He grant one that recites the Psalms that be considered as if the person had studied the Laws of Negaim and Ohalot (Tehillim 1).
